I'll buy it at some point, probably not long before ME3 is released to refresh my memory. It was a great game, but the only DLC that really seemed worth making a priority was LotSB. Going back to a game just to play 1 or 2 hour snippets doesn't really interest me that much, so I'll be going through this, Overlord and the Kasumi DLC when the time comes.

Same here. I really have yet to see a DLC that makes me think "Oh, gotta get that now!" Cause by the time the DLC does roll around, I've already beaten the game and moved on.

By lasting appeal, I mean anything that keeps the game from falling into the abyss of time. This is by no means associated to the company and not always linked to re-playability. Let me use a small example to demonstrate this:

How much fanart of ME2 is there per week? 10?How much fanart of FF7 is there per week? 1000+How much fanart of Touhou is there per week? 10,000+

Who do you think will survive the passage of time? Oh wait, the competition is at least 10 years older and still more alive.

I also doubt the people that got the game at release are still playing. I played it twice and I don't think I'll want to give it another run for a long long time.
